This would be way to op as stated above. People would be able to rush fairly easy in the game, and during late game, it's going to be a pain. Let's say the your trying to break an egg. The team your breaking has that kit. You killed the person. He spawns in with chain gear. It will be impossible to kill him.

Also, most of the players that have enough points to purchase this are the experienced players. You have all the good players using tank kits while new players have weak ones. It's obvious this won't be added.

This would be too overpowered, You would always get rushed and this would ruin all the other kits as it would be used all the time. What Is the point of having egg armour if alternatively for a few extra points you get a far stronger kit.
